Abstract
The present invention is Emulsion Adhesive composition and the releasable adhesive sheet using described binder composition, the feature of described Emulsion Adhesive composition is, containing making containing 2-EHA, the acrylic copolymer (A) that Monofunctional monomers's mixture of butyl acrylate and ethylenic unsaturated carboxylic acid and polyfunctional monomer carry out letex polymerization and obtain and tackifying resin (B), wherein, the mass ratio (2-EHA/butyl acrylate) of 2-EHA and butyl acrylate is 0.6 ~ 2.5, the softening temperature of above-mentioned tackifying resin (B) is 130 ~ 180 DEG C.According to the present invention, also there is high adhesion even if can provide to uneven surface, and there is the binder composition of enough force of cohesion, and use the releasable adhesive sheet of described binder composition.
Description
Technical field
The present invention relates to and be applicable to the Emulsion Adhesive composition used and the releasable adhesive sheet using this binder composition when preparing the sign label etc. of tire.
Background technology
Commodity indicate label and are glued to commodity etc. for transmitting trade(brand)name or out of Memory.In the past, indicate label as such commodity, extensively utilize the adhesive sheet in substrate with binder layer etc.
For such adhesive sheet, require to have have high bounding force when commodity circulation, but finally can peel off relatively easily, do not produce the characteristic of cull.
Therefore, in the adhesive sheet requiring these characteristics, carried out various research to forming the tackiness agent of adhesive sheet or caking agent etc. up to now.
Such as, Patent Document 1 discloses the pressure sensitive adhesive composite be made up of specific acrylic emulsion polymer, anionic emulsifier and nonionic emulsifying agent, record the excellent cementability of said composition display and removeability.
In addition, Patent Document 2 discloses containing making specific acrylate, vinyl cyanide and α under the existence of anionic reactive emulsifier, the acrylic emulsion pressure sensitive caking agent of the ACRYLIC EMULSION that beta-unsaturated carboxylic acid carries out letex polymerization and obtains, records this caking agent and is difficult to produce cull on adherend.
Like this, although also can realize the raising of the performance of tackiness agent or adhesive sheet at present, due to the kind of adherend, all there is the hypodynamic situation of bonding in general adhesive sheet.
Such as, the sign label of tire records manufacturers's title, trade(brand)name, size etc., be pasted on the tyre surface of tire, but the tyre surface due to tire has very large concavo-convex, and the tyre surface of tire there is the venting port of mould because using when tire building and formed be called " burr " must shape thrust, so bond area is quite little.Because the distinctive shape of this tire significantly reduces the bounding force of adhesive sheet, so by when using in above-mentioned document the adhesive sheet of the caking agent recorded to be pasted on the tyre surface of tire, there is the not enough and problem easily peeled off of bounding force.
In the past, in tire adhesive sheet for bonding, many use rubber solvent class tackiness agents.But, use the adhesive sheet of rubber solvent class tackiness agent with an organic solvent to exist because of many and make cumbrous problem to environment.In addition, owing to using tackiness agent for raising in a large number to the bounding force of tire, reduce the force of cohesion of binder layer, so also there is the problem peeling off rear cull.In addition, adding man-hour to adhesive sheet enforcement label, also there is the bite of adhesive attachment in cutting machine or the guide groove etc. of printing press, polluting the problem of adhesive sheet etc.Although this pollution problem solves by comprehensive coating process being replaced with part coating process (being partly coated with and make tackiness agent not be present in the method for predetermined place of incision), now production efficiency will significantly reduce.
In addition, it is also proposed the tire adhesive sheet for bonding using the new tackiness agent replacing rubber solvent class tackiness agent in recent years.Such as, Patent Document 3 discloses the adhesive sheet with the binder layer that blending liquid tackifying resins is cross-linked in specific acrylic resin.But this adhesive sheet also reduces force of cohesion for improving binder layer relative to the bounding force of uneven surface, has the problem of cull.

The tackifying resin (B) of (i) emulsification that hybrid regulatory is quantitative in the polymerization liquid being prepared acrylic copolymer (A) by emulsion polymerization and the tackifying resin of other emulsification optionally, prepare the method for Emulsion Adhesive composition
(ii) tackifying resin (B) and other tackifying resin is optionally made to be present in advance in emulsion polymerization systems when preparing acrylic copolymer (A), by directly carrying out letex polymerization, prepare the method for Emulsion Adhesive composition
(iii) other tackifying resin is made to be present in advance in emulsion polymerization systems when preparing acrylic copolymer (A), carry out letex polymerization, after polyreaction terminates, the tackifying resin (B) that mixing and emulsifying is crossed prepares the method etc. of Emulsion Adhesive composition.
Wherein, due to polyreaction can be controlled, and do not lose tackifying resin (B) characteristic, so the method for preferably above-mentioned (iii).
Emulsion Adhesive composition of the present invention, owing to having enough force of cohesion, so be different from the existing adhesive sheet of force of cohesion raising to the compliance of uneven surface reducing binder layer, is difficult to produce cull after release adhesive sheet.
In addition, add at label and there is not binder composition man-hour and be attached to the bite of cutting machine or the guide groove etc. of printing press, pollute the situation of adhesive sheet etc.
2) releasable adhesive sheet
The feature of releasable adhesive sheet of the present invention is, described releasable adhesive sheet is the releasable adhesive sheet at least with substrate and binder layer, wherein, above-mentioned binder layer uses the Emulsion Adhesive composition containing aforesaid propylene acid copolymer (A) and tackifying resin (B) to obtain.
Releasable adhesive sheet of the present invention is after being bonded in adherend via binder layer, the adhesive sheet can peeled off again from adherend.
[substrate]
As the substrate used in the present invention, without particular determination, known plastics film or paper, synthetic paper etc. can be used.Wherein, due to mechanical strength, effectively can prevent the destruction of substrate when peeling off, so be preferably plastics film or synthetic paper.
